The referee is expected to show what kind of approach when penalizing for infractions?

The referee is expected to show a firm and decisive approach when penalizing for infractions, which is why the correct answer is to act without hesitation. This approach ensures that the rules are enforced consistently and that wrestlers and coaches understand the seriousness of the infraction. Immediate action helps maintain the flow of the match and reinforces the authority of the referee, allowing competitors to recognize the consequences of their actions without ambiguity.

In contrast, delaying a response can lead to confusion and disrupt the match's rhythm, while relying solely on verbal warnings or waiting for confirmation from an assistant can undermine the referee's role and authority. The ability to act promptly and clearly communicates to everyone involved that the rules are being upheld, which is essential for fair competition.
